This is just getting dumber and dumber the more specific his complaints get. "Statistics lie" is the midwit excuse of people who don't appreciate that statistics can only give precise answers to precise questions. Enrolment rates, international vs domestic student rates, graduation rates, are all valuable data points if your question is "How do Japanese colleges differ from all other countries' colleges", but Kamo wants to actually ask something like "what is the future value of choosing, today, to enrol in a Japanese higher education program - for a Japanese citizen of a specific age and specific economic outlook" (and he wants to do it with his typical center-right bias). That's why he suddenly starts talking about the 'value of college' and saying that graduation rates are much more relevant.
Statistics are unreliable and misleading if you ask really dumb questions, like Kamo.
